Luke is a Yorkie who lives with Grace and her mom and Bryan. He is very wild and playful and is very much a puppy. He used to live with Grace’s mom’s friend Tiffany, but then he got territorial and started trying to bite the other, bigger dog named Henry, and so Grace and her mom adopted him. Luke loves Grace and likes to hang out with her upstairs while she plays on her electronics or does homework. He used to be scared of the other smaller, and much older, Maltese dog in the house, Coconut.
